It sounds there is a convertiion issue with a boolean value. Can you provide some more information?


Hi Darshan,


Not sure if you’re still looking for the solution.

I was trying to upgrade to 8.18.8.

I had the same issue while upgrading from 7.23.8 to 8.0.0.

I later on upgraded the version to 8.18.8 and the same issue doesn’t happen again.
